Sooooooooooooooo......who is dumb enough to lend him the money?
There may be some short term borrowing, but long term I fully expect congresscritters to enact means testing, meaning if you make more than $10K a year, own your home or have a net worth over a dollar and a quarter, wave bye-bye to all the money you paid into Socialist (in)Security. You won't see one penny of it. They'll also raise the age of eligibility to the point where most folks die off long before they ever collect one red cent.
I'd gladly, nay, gleefully give the gubmint every dime I've paid into the Socialist (in)Security Ponzi scheme over the past 30 years if they would just let me out! I'm about to turn 47 and there is still time for me to significantly add to my own retirement funds if only I didn't have to pay both sides of Socialist (in)Security.
